Emma’s Post-Crimbo Pie

China Central Television has produced a short video showing the plant experiments growing on the Tiangong space station. The Shenzhou-16 crew has been in orbit for almost three months, and says their space vegetable garden has given a good lettuce harvest.

An ideal seed compost is able to retain water, whilst at the same time letting excess water drain away to provide an environment that is damp but not waterlogged. It allows penetration of plant roots and is able to anchor plants, but has space for air. Its texture is consistent, and it is free from pests, diseases and weeds that would compete with the seedlings. As we have seen, it doesn’t need to contain many nutrients if seedlings are going to be pricked out; seedlings growing in modules will either need enough nutrients in the compost to support them through their first weeks of life, or suitable supplementary feeding.

Sometime towards the end of last year, my friend Chris gave us a homegrown, blue pumpkin. I’m amazed to find that I don’t have a photo of it, but it was large, a fairly traditional pumpkin shape, and rather spiffingly blue. It sat on the dining room table for months, waiting for me to pluck up the courage to do something with it, which eventually happened last week.

Join Emma the Space Gardener as she explores gardening on Earth… and beyond! In this episode, Emma recaps the latest space plant news and then talks about some of the seeds with space stories.

One of the big differences between now and the time before gardeners relied so much on peat-based composts is the rise in container growing. An army of modern amateur gardeners has to put up with small gardens, and possibly with no soil at all. Growing plants in containers allows us to garden wherever we like, and even to grow plants that would not thrive in our soil. Some plants are grown in containers to keep them under control; others so that they can be moved indoors in winter to ensure their survival.

Ericaceous compost

Whenever I see demonstrations of composting on TV I’m always impressed by three things – the size of the compost heap, the endless supply of compostable materials to put on it and the enormous vigour of the gardener in charge of the heap.

When the sun shone on Saturday morning, and the rain promised to delay until midday, we hatched a plan to build two more of the raised beds in the garden. One half of the garden – 6 beds – was completed last year, leaving 6 more to go. We don’t have space for them all until we take the old shed down, but we found room for two next to Ryan’s workshop.

Move over, Mark Watney, there’s a new space botanist heading for Mars! Ryan and I have just finished watching the new Netflix series Away, which follows (over 10 episodes) the quest of five international astronauts to be the first people to set foot on the red planet.

Gardeners are privileged to witness miracles on a daily basis – seeds germinating, buds unfurling and bees pollinating flowers. No less miraculous are the quiet miracles that take place in the compost heap, where tiny organisms turn waste products into compost, allowing the cycle of life to begin again.

I’ve got a brand new compost tumbler… and the Wurzels stuck in my head:

If you’ve got a small garden then you might find it difficult to find space for a conventional compost heap. A possible solution is a worm compost bin, which takes up far less space because an army of worms does most of the composting work.
